CARBURETER.

To all whom it may concern:

Be it known that I, PAUL Bosman, a citizen of the United States, residing at Fred` erick, in the county of Tillman and State of Oklahoma, have invented a new and useful Carbureter, of which the following is a specicat-ion.`

This invention relates to carbureters of that type in which air is forced through a will be impossible to flood the engine with gasolene or wet gas, and also to provide a 'carbureter in which a perfect mixture of air and hydro-carbon vapor is effected, thereby enabling the engine to start on the first com'- plete cycle.

Another object of the invention is to pro* vide a carbureter in which all gas pumps andpipes, as well as needle valves and iioat feeds are dispensed with, the apparatus beingl an devoid of'movableparts to wear out, get loose or out of order.

The invention also'has for its object to provide a carbureter embodying certain novel structural details, resulting 1n greater efficiency, as will be hereinafter described and claimed.

` In the accompanying drawings, forminga part of this speci'cation, Figure 1 is a vertical section of a carbureter constructed 1n accordance with the present invention. Fig. '2 is ahorizontal V Fig.' `1.

section on the line 2-2 of 1n the drawings, 5 denotes a tank which contains the supply of gasolene or other hydro-carbon, the tank being provided with a Y filling tube 6 entering through the top thereof, and provided'with a suitable closure 7. 1n the `tank `is a false bottomS to form a water chamber 9, this chamber being located below the false bottom and the supply of gasoleney being located in the tank above the said false bottom. The wat-er chamber is provided for the purpose of heating the gasolene to promote vaporization. Varm water is introduced into the chamber through a pipe 10, and it leaves the chamber through a pipe 11, the outlet and inlet ends of said pipes being located respectively ad- Specification of Letters Patent.

jacent to opposite ends of the chamber, whereby a circulation is maintained therein.

Above the false bottom 8, the tank bacontains horizontal partitions 12 and 13 res ectively, which are spaced from each ot er, and connected by a circular series of air tubes 14 opening therethrough. One of the ends of the tubes opens into the space between the partition 12 and the false bottom 8, and the other ends of the tubes open into the space above the partition 13.

Located centrally between the partitions 12 and 13 is a perforated tube 15. The di anieter of the tube is considerably-greater than the .diameter of the tubes 14, and the latter extends in a circle around the same adjacent to the tank wall. The partition 12 has perforations 16 which are locatedin the central part thereof covered'by the tube 15. The partition 13`has perforations 17 which extend throughout the entire area thereof, including that portion of the partition which is over the tube 15. y

Above the partition `13, the tank 'contains a partition 18 formed ofabsorbent' material which is held between gratings 19. This partition of absorbent material extends entirely across the interior of the tank, and above the same is located a pair of screens 2() also extending entirely-.across the nterior of the tank.

nnissunn 1 Above the screens 20, the tank 5 is entered by an air supply tube 21 provided with a valve for controlling theamount of air entering the tank, said valvecomprising a sleeve 22 mounted for rotation on the tube 21, and having a slot 23 adapted to register more or less with a slot 2 in the tube.

Below the air tube 21, the tank 5 circled on the outside by an air chamber 25, said air chamber being mounted on the tank in any suitable manner, and being annular in form. This chamber is entered by one or more air supply tubes 26 provided with a valve 27 similar to the valve 22 already described. From the air chamber 25, pipes 28 lead into the tank 5, below the partition 12. A plurality of pipes 28 are provided, they extending in a circular series around the tank on the outside thereof. On the top of the tank is mounted an outlet pipel 29 having a laterally directed i branch 30 which is connected to the "suction pipe 31 of the engine (not shown). The pipe 29 is properforated diaphragm 33 located in the pipe 29 above the pipe 30. The upper end of the pipe 29 is closed by a perforated screw ca p 34, and between this cap and the valve is interposed a coiled spring 35 for holding said valve seated.

In operation, the tank 5 is filled with gasolene up to within a short distance from the partition 13. On the suction stroke of the engine, air is drawn down the tubes 2S from the chamber 25 into the gasolene, and then passes upwardly through the tubes 14 which are partly immersed in the gasolene. Particles of gasolene are carried upwardly with the air against the partition 18, which thus becomes saturated with gasolene, so that the air passing therethrough is oarbureted. The carbureted air passes through the screens 20, and upon meeting the incoming current of air entering the tank through the tube 2l commingles therewith and passes in a pel'- fectly dry state to the engine. The valves 22 and 27 will be set to admita proper volume of air, and after they are set, the engine may be started any number of times without further adjustment. The air upon entering the body of gasolene below the partition 12, also passes through the perforations 16 into the tube 15, and outof the latter through the perforations thereof intoy the space between the partition 1.2 and the partition 13,-and thence through the perforations '1T in the latter partition. The air-is thus spread through the gasolene, and the latter is carried to all parts of the partition 18. Thegasolene does not all go through the partition 18 andthe screens 20, a partof it drippingy down onto` the partition 13, and through thel perforations 17 back ply. The gasolene is mixed and broken up in going up against the absorbent partition and the screens, and also when dropping back to thetank bottom, so thatv there is no waste. The perforations 17 are flared in the direction of the partition 18, and their diameter is relatively small at their lower ends,

so that the unused gasolene can drip down to the tank bot-tom, and is prevented from being violently thrown upwardly through the perforations.

A carbureter constructed as herein described, makes it impossible to flood the engine with gasolene or wet gas, and the engine runs cool, and develops a maximum amount of power, using only pure dry gas, which `also prevents carbon deposits on the cylinder and cylinder head, and reduces friction to a minimum. The apparatus is also simple in construction, all gasolene pumps, pipes, float feeds and needle valves being dispensed with, and there being no movable parts to get. loose or out of order. The efficiency of the apparatus is not affected by Water or other impurities in the gaso- `partitions in the tank, one

to the suplene, as the partition 18 and the screens 20 separate the same.

To the bottom of the tank is connected a pet cock 37 for drawing off the gasolene when it is desired to empty the tank, and also any impurities which may collect in the tank.

The apparatus can be used on any internal combustion engine, and can be made in anyr form and size.

lVhat is claimed is:

1. A carbureter comprising a tank, spaced partitions in the tank, a perforated tube mounted between the partitions, one of said partitions beingI perforated throughout its entire area, and the other partition having perforations in its part which is covered by the aforesaid tube, ilnperforate tubes extending between the partitionsl and opening therethrough, air supply pipes entering the tank below the` partitions, anda partition of absorbent material located above the aforesaid partitions.

2., A carbureter comprising a tank, spaced partitions in the tank, tubes extending between the partitions and opening ltherethrough, an annular air chamber encircling the tank on the outside thereof, valve-oontrolled inlets ,to the chamber, )ipes leading fromrthe chamber into the tank below the partitions, and a partition of absorbent material above the aforesaid partitions.

3. A carbureter comprising a tank, spaced of said partitions being perforated, a perforated tube mounted between the partitions, and opening therethrough, and imperforate tubes extending between the partitions and opening therethrough, air supply pipes entering the tank below the partitions, and a partition of absorbent material located above the partitions.

4. A carbureter comprising a tank, spaced partitions in the tank, a perforated tube mounted centrally between the partitions, one of said partitions being perforated throughout its entire area, and the other partition having perforations in its part which is covered by the aforesaid tube, a oircular series of imperforate tubes extending between the partitions around the perforated tube, and opening through said partitions, air supply pipes entering the tank below the partitions, and apartition of absorbent material located above the partitions.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.
